The electron configuration of iodine (I), which has an atomic number of 53, is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵. This configuration indicates that iodine has a total of 53 electrons, filling the respective energy levels and subshells according to the Aufbau principle. The presence of five electrons in the 4p subshell is characteristic of its reactivity as a halogen.
